题目内容
________that you come here earlier tomorrow or you'll be in trouble.
A.Be sure of B.Make sure
C.It's sure D.Make sure of
B
【解析】句意:明天确保早点儿来,否则你就会有麻烦的。make sure“确定;确信;查明;弄清楚”,后可接that从句(that可以省略)或of sth.。sb. be sure of sth.“某人对某事有把握”,后接名词或介词作宾语;It's sure that不存在,sure的主语常用sb.,不能用主语从句。此时可用certain代替,用It's certain that...意为“……是一定的,有把握会……”。
